Abstract (en)

A low noise roller chain (1) includes a rigid roller (17) made of metal and an elastic roller (18) made of elastic material that are arranged end to end and fitted on a bushing (13) between two opposed inner plates (14) so as to jointly form a roller assembly (19). The width (W) of the elastic roller is 13 to 45% of the overall width (W+w) of the roller assembly (19), and the thickness of the elastic roller (18) is larger [by 5 to 25%] than the thickness of the rigid roller (17) by 5 to 25% of the thickness of the elastic roller (18). With the elastic roller (18) thus constructed, noise generated upon abutment of the roller chain with a sprocket can be effectively suppressed without deteriorating the durability of the rigid metal roller (17). The elastic roller may be arranged in a zigzag pattern in the longitudinal direction of the roller chain.
